Spain's Robredo, seeded 16th in the US Open tune-up, sent top-seeded Djokovic packing 7-6 (8/6), 7-5, the defeat coming a week after the World No 1 Serb was beaten in the third round at Toronto.

The Wimbledon champion now goes into the US Open, the final Grand Slam of the year which starts on August 25, well short of matches and confidence.
